The next day, Saginaw Township police arrested, 48-year-old Bradley J. Traxler, who shares an address with Braddock, according to arrest records. Traxler was in Kozak's vehicle, police said.

Traxler's booking on a parole violation came less than 10 hours after Kozak was discovered, Saginaw County Jail logs show. Traxler, of 723 S. Warren in Saginaw, was booked at 7:31 a.m. Saturday, Aug. 17.

Kozak's death remains listed as suspicious. Traxler has not been named as a suspect in her death.

"One of my officers observed a vehicle that was tagged with a 'be on the look out for' on it,” said Saginaw Township Chief Donald Pussehl.

A Saginaw Township officer pulled over the vehicle, a 2001 GMC Sierra pickup, at 11:10 p.m. Friday, Aug. 16, at T.G.I. Fridays, near the intersection of Bay and Tittabawassee, Lt. Gary Grauf said.

The vehicle was confirmed as registered to Kozak, and township officers turned it over to city police, Pussehl said. There were two people in the vehicle, Pussehl said.

“Saginaw police are in charge of the suspicious death investigation, so we turned the vehicle and two occupants over to them,” Pussehl said.

Saginaw Township officers stood by while Saginaw Police Department detectives interviewed the two men separately, Grauf said. City police lodged Traxler and released the other occupant of the vehicle, he said.

An autopsy to discover the cause of Kozak's death was inconclusive, Saginaw police spokesman Detective Sgt. Reggie Williams has said, and authorities await toxicology reports to learn more.

Williams declined comment Aug. 22 about Traxler's arrest.

Braddock, who served on the Saginaw police force from 1983 to 1991, said he doesn’t know anything beyond what he already has told police — that he found a body in his driveway on Friday, Aug. 16, upon returning from a brief vacation. He called police after finding the body.

“I told them what I know,” Braddock said. He declined further comment.

The Saginaw Police Department and the Michigan State Police jointly are investigating.

Michigan State Police Lt. Brian Cole called it an "ongoing investigation."

Kozak was recently an employee of Saginaw Medical Credit Union for 23 years, according to CEO Missey Kelly.

Braddock, who also worked for the Michigan Parole Board, said he has lived at the address for 33 years.
